1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

purposeThe aim of this study was to assess the potential influence of single nucleotide polymorphisms (SNPs) in the TLR4 gene on tacrolimus pharmacokinetics in the early stage after liver transplantation.

methodsA total of 96 liver transplant patients receiving tacrolimus-based immunosuppressive regimens were enrolled in this study. The SNPs of CYP3A5 rs776746 and TLR4 rs1927907 were genotyped in both donors and recipients. Trough tacrolimus concentration (ng/mL) and tacrolimus daily doses (mg/day) were recorded for the first 4 weeks post-transplantation. The tacrolimus dose-adjusted trough concentrations (C/D ratio) required to achieve target concentrations were compared among patients according to allele status for CYP3A5 rs776746 and TLR4 rs1927907 during the first 4 weeks post-transplantation.

resultsBoth donor and recipient CYP3A5 rs776746 allele A and donor TLR4 rs1927907 allele A were associated with a lower C/D ratio during the early stage after transplantation. The difference was even more striking in patients with both the CYP3A5 and TLR4 genotypes. With increasing numbers of genotype AA/AG, patients were found to have increasingly lower tacrolimus C/D ratios at all time points between post-transplantation weeks 1 and 4.

conclusionsCollectively, donor TLR4 rs1927907 SNPs were closely associated with tacrolimus elimination in our Chinese Han patient population. The combination of the donor TLR4 rs1927907 SNP and both donor and recipient CYP3A5 rs776746 SNP might have a greater effect on tacrolimus elimination than each SNP separately. Screening for these SNPs prior to liver transplantation might be useful for determining adequate initial daily doses of immunosuppressive agents and achieving the desired immunosuppressive effect.
